The noise is really only unbearable on concrete surfaces, so much so that the bluetooth phone function becomes unworkable because of the competing road noise. Once I got out of the Seattle area and hit the newer asphalt surfaces it was much, much better.
Bill, I picked up the car in Seattle and drove home to MT, where I live at 5000ft, so the pressure is good. I'll bet it was lower when I started, though.
Dan, that's a good tip. That's really all I want to do is make it more livable.
And Brian...thanks for all you do! It's really great for a first time owner like me to find your site.
